The specific binding of 125I-labelled [D-Ser(tBu)6,des-GlyNH2(10)] LHRH ethylamide (LHRH-A) to testicular intertubular cells fractionated on Percoll density gradients was investigated. The greatest binding per cell occurred in the density region whic

Ewes with permanent phyto-estrogenic infertility show oestrus less regularly than normal ewes, and the present study examines the extent to which this results from abnormal ovarian function. Forty-nine affected ewes and 53 controls were run with rams

Intravenous infusion of 4.5-4.7 mg of mouse epidermal growth factor (mEGF) into nine castrated male Merino sheep for 26 h resulted in complete casting of the fleeces 6-8 days later. The morphological changes which occurred in the skin were studied in

Previous studies from this laboratory have implicated the sympathetic neurotransmitter noradrenaline (NA) in regulation of wool growth. The current study was undertaken to investigate [3H]NA accumulation and its localization by Merino skin, and to de
